LEDs do not dim with available power. They are only on or off. There are ways of dimming LEDs, but they all involve some type of circuit that is performing a PWM function (essentially turning the power on and off at a high enough duty cycle so as to appear to the eye as always on).

It would probably be possible to install two sides of a contact switch on the console and the base so that the lights turned on only when you opened the console, but that'd probably be a fair amount of work for not a ton of benefit.
